“But you can get in touch with every town to the north, and pick up pointers here and there!” Percy declared, excitedly.  “Get back to town as fast as you can, Chief, and with a couple of your men I’ll carry you wherever you want to go.  In the meanwhile, you can leave orders for your men to do the wiring business; and whenever we strike a town we can ring up Headquarters over the ’phone, and learn what news they’ve managed to pick up.”

Percy seemed to think that all he had to do was to tell the Chief what he wanted; but then his plan of campaign was really a good one, and the police officer was wise enough not to quarrel with his bread and butter; for the Widow Carberry was a large property owner in Bloomsbury.

“You just take the words out of my mouth seems like it,” he remarked; “and that is the best plan we could carry out.  I was just going to suggest to Frank and Andy here, that if they felt like taking a little spin off to the northward this fine morning, and discovered anything suspicious, they could get word to us, perhaps through the Bloomsbury Central, for we’ll be apt to keep in touch with home.”

Percy did not know whether to look pleased at this suggestion or not.  It would be just like the everlasting luck of the Bird boys to make another remarkable success out of this thing, for they seemed to have a failing that way, while all the hard fortune came in his direction.  That would give him a pain to be sure, for he was horribly envious of their local fame as successful aviators; but at the same time he hated to lose that beautiful biplane, which he had not owned very long, and which had taken his heart by storm.

So Percy finally compromised, as he frequently did.  He even forced a grim smile to appear upon his face, though it did not deceive Frank in the least; and as for Andy, he never took the least stock in Percy Carberry’s honesty.  In his mind there was always a deep meaning underneath every action of the other.

“Why, sure I hope Frank will discover the thieves, and recover the stuff they’ve grabbed from the bank; also that he’ll have the good luck to get back my biplane without its being badly wrecked.  That reward is worth trying for, and I don’t go back on my word.”

All the same he knew very well that neither of the Bird boys could be forced to ever accept one penny from his hand, no matter what good Dame Fortune allowed them to do for him.

Andy was watching keenly when the Carberry boy walked back to his machine, and climbed into the steering seat.  Frank, happening to look that way, saw his cousin’s face lighted up as if in glee:  and he even heard him chuckle.  Perhaps Percy may have caught the same sound, for he turned his head after dropping down into his seat, and scowled darkly at Andy.  There is nothing like a guilty conscience to bring about a self-betrayal; and somehow Percy seemed to know what the Bird boy was thinking about just then.
